SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 516,957, dated March20, 1894.

Application filed October 28,1893. Serial No. 489,336- (No model.)

To all whom it may concern.-

Be it known that I, ELZIE AMENT, a citizen of the United States,residing at Rogers Park, in the county of Cook, State of Illinois, haveinvented certain new and useful Improvements in Sash-Fasteners, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to certain new and useful improvements in sashfasteners of that class embodying a slotted strip on the one part and alocking bolt on the other part having means for quick engagement ordisengagement thereof, and it has for its objects among others toprovide an improved fastener of this description by which the sash canbe readily held at any desired point, without any particular care beingtaken to have the parts in just such a position as is necessary wherethe guide is toothed and the locking bolt must be in position to engagea particular tooth. In order to secure an absolutely sure hold or grip Imake the outer end of the bore in the base through which the lockingbolt works vertically elongated so that after being tightened in theusual way with the fingers the bolt may be moved downward at its pointor head out of its horizontal plane, becoming tighter as force isapplied to the sash to move it upward. I also provide a spring arm whichembraces with its right-angled bifurcated portion a squared portion ofthe bolt between shoulders thereon, and this spring serves to hold thebolt in a horizontal position, it prevents the bolt from turning, and,in conjunction with the shoulder on the bolt, it prevents too great aforward longitudinal movement of the bolt.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon,form a part of thisspecification and in which Figure 1 is a front elevation of a portion ofa window with my improvement in position, and the lower sash partiallyraised. Fig. 2 is a longitudinal section of my improvement on the line22 of Fig. 1, somewhat enlarged.

Fig. 3 is a cross section on the line 3-3 of Fig. 2, looking up. Fig.4isa perspective detail of the sliding bolt and the spring arm.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates aportion of a window frame and B a portion of the sash.

My invention is applicable to various uses; it may be arranged upon thetop of the lower sash with the guide upon the face of the upper sash; inthis position it will serve to lock the two sashes together and thelower sash can be locked part way up or the upper sash locked part waydown, or both locked open a little distance; .or, instead of being thusarranged, the guide may be on the lower sash near the lower end and thebolt and its operating mechanism secured to the side of the frame. Theguide is open at one end so as to permit of the sash being opened as faras desired. It the guide is arranged near the lower end of the sash the.open end of the guide should be downward, but if the guide is arrangednear the upper end of the sash the open end should be uppermost; whenthe lock is on the top of the lower sash and the guide on the upper sashthe open end should be uppermost. In the present instance the guide isshown as upon the upper sash and the bolt upon the upper face of the topcross .bar of the lower sash.

O is the channeled guide of any desired length and as fanciful asrequired, provided with the holes 0 for the reception of the screws orother means 0 by which it is secured in place. It is formed with thelongitudinal slot 0' open at one end as seen at c and that endpreferably beveled or tapered to facilitate the entrance of the head ofthe bolt into the slot as will be readily understood. The flanges C ofthe guide are not notched or toothed but are left plain as shown.

D is a casting or base provided with flanges d, having holes 01' for thereception of the screws or other means 01 which fasten it in place. Thisbase or casting is provided with alongitudinal chamber or bore in whichis arranged the bolt E, which has a screw-threaded opening or chamber eat one end and at the other end a head E with a tooth e as seensiefe'e'r best in Fig. 4: to engage the inner faces of the flanges G ofthe guide as seen in Figs. 2 and 3.

F is a screw having at one end a screw threaded portion to engage thethreads of the chamber 6 of the bolt as seen in Fig. 2, and, outside thebase or casting, provided with a flange f as seen in Fig. 2 to bearagainst the outer end of the base or casting, and with a milled portionF by which it may be turned when desired. Within the base or casting thescrew is formed with an annular groove f in which works a screw G heldin the base or casting as seen in Fig. 2 and which will permit ofrotation of the screw and still prevent its longitudinal movement.

' The bolt E has between its ends a squared portion E as seen best inFig. 4, and H is a spring arm held at one end in any suitable manner, asfor instance by the screw G as seen in Figs. 2 and 3 to the base orcasting and its other end is turned at a right angle to the length ofthe arm and is notched or bifurcated as seen at h in Fig. t and thisbifurcated or notched portion embraces the squared portion ofi the boltand serves to hold the bolt in its horizontal position, to prevent thebolt from turning, and, in conjunction with the shoulder on the bolt,limits its forward longi tudinal movement.

The outer end of the bore or opening of the base or casting throughwhich the screw and bolt work is somewhat elongated vertically so thatthe bolt after being tightened with the fingers in the usual way can bemoved downward at its head or point, out of its horizontal plane so asto more securely hold the sash in place.

The operation will be readily understood. The turning of the screw inone direction or the other moves the bolt in or out; when it is desiredto raise or lower the sash the screw is turned so as to disengage thetooth of the bolt from its engagement with the flanges of the guide whenthe sash is raised or lowered to the desired position and a few turns ofthe screw will bring the tooth of the bolt into contact with the flangesof the guide and firmly hold the sash in position.

Modifications in detail may be resorted to without departing from thespirit of the invention or sacrificing any of its advantages. Forinstance, by shortening the guide to say about one inch in length, so asto allow from one quarter to one half an inch for obstructions under thesash, and with a suitable base for fastening the guide to the meetingrail of the upper sash the fastener may be used in the center of thesash in the same manner as other meeting rail locks are used.

What I claim as new is- 1. The combination with a slotted guide havingsmooth-faced flanges, of a base with a sliding bolt with a head havingteeth to engage said flanges, and a screw mounted for rotation and heldagainst longitudinal movement and engaging said bolt to actuate thesame, substantially as specified.

2. The combination with a slotted guide having flanges, of a base with asliding bolt, a screw mounted for rotation and engaging said bolt tomove the same longitudinally, and a spring arm held at one end and theother end engaging the bolt, as and for the purpose specified.

3. The combination with the flanged slotted guide, of a base, a boltmounted to slide therein and havinga head with teeth and a squaredportion, a screw mounted for rotation to move the bolt longitudinally,and a spring arm having a right-angled end bifurcated and embracing thesquared portion of the bolt, substantially as specified.

4. The combination with the slotted guide open at one end and havingplain faced flanges, of the base having longitudinal bore verticallyelongated at one end, a bolt mounted to slide in said base and to havevertical play therein, and a screw mounted in the base for rotation andheld against longitudinal movement, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ELZIE AMENT.
